-------------------------------------------
I am facing the same issue
Every time i try to install a package that contains multiple uuids i get the exception in packagemanager.
{code}
Error during processing:

Error: org.apache.jackrabbit.vault.packaging.PackageException: javax.jcr.nodetype.ConstraintViolationException: OakConstraint0030: Uniqueness constraint violated at path [/] for one of the property in [jcr:uuid] having value 8cc22e40-bfac-4feb-8164-f45796f88996
{code}
When i search for the uuid in crxde i get the results in /jcr:system/jcr:versionStorage/...
When i remove one of the uuids from the package manually (by editing the .content.xml file) and try to install the package, the next uuid from that package is shown in the error message.
Unfortunately i can not reproduce that behaviour on another instance.
